OpenStreetMap.org

The most basic way to use OpenStreetMap on your Mac is to open http://www.openstreetmap.org/ in a Web browser such as Safari. The iD editor embedded on the website supports basic editing of OpenStreetMap, but you may find a desktop editor to be much more convenient for more advanced editing, such as imports.

OpenStreetMap applications

The following applications rely on OpenStreetMap for core functionality, so they’re good ways to use OpenStreetMap on your Mac.

Viewing maps

These applications focus on viewing various OpenStreetMap-based maps. Some of them also allow you to cache maps for offline usage.

RubiTrack - Designed for organizing and tracking your sports activity. Import from several Garmin devices and iPhone. Can export GPX files. Version 1.x still uses Google Maps for tracking. Since Version 2.0 OSM Data can be also viewed.

RubiTrack Support direct import from Garmin (including TCX). Also has embedded GPSBabel for other formats. Can export GPX. Currently doesn't use OSM as source of maps (just Google), but developers say that OSM will be later.
